' This invention relates to a device which limits the angular degree of opening of a door hinge, and particularly to a device which fits over a door hinge and opposes its opening after a certain angle has been reached.

A door stop usually consists of a rubber-tipped metal'rod extending outward from either the base ofla'door or the wall in back of a door. This prevents a door from opening too wide whereby the doorknob may strike the wall and damage the plaster. While these door stops prevent injury to the plaster, they do not adequately protect the door which is frequently sprung out of line by striking the metal rod with too much violence. Another objection to the metal rod door stop installed in the wall is that it has an area on the floor "around'it which is difficult to clean due to the presence thereof.

Accordingly, it is'an object of this invention to provide a. door stop which avoids these disadvantages.

Another object of this invention is to provide a cheap, easily made, and effective door check which attaches to a door hinge and limits the angle to which the door hinge will open.

A further object of the invention is to provide a door check which attaches to a door hinge and which may be adjusted to fit a wide variety of hinge lengths.

A still further object of the invention is .to provide a door check which attaches to a door hinge and which may be deformed to change the angle to which the hinge will open.

Other and further objects of the invention will become apparent to those skilled in the art from the following detailed description of the annexed sheet of drawings which discloses preferred embodiments of the invention.

On the drawing:

Figure 1 is a view of the hinge and check in position on a door;

Figure 2 is a top cross-sectional view taken along the line IIII of Figure l and showing the hinge plate impinging upon the edges of the door check; and s Figure 3 is a perspective view of the door check showing how the two members are in telescopic relation with each other to provide a wide variety of sizes of hinge to which the device may be adapted.

As shown on the drawings:

The device of this invention may be constructed of two pieces of sheet metal as best shown in Figure 3. An insidemember I is formed to telescope into an outside member ll. These sheet 6 Claims. (01. 1 -137) metal members are preferably formed into rounded or semi-circular channels. The edges l2 of the outside member H are folded loosely over the edges of the inside member Ill and the member I] thus defines a track upon which the member [0 may slide in telescopic fashion.

It is preferable, although not necessary, that the members l0 and l I be prevented from separating. This is accomplished by prow'ding lugs along the edges of the two members at the point where they would otherwise be separated. In the case of the outside member H a lug 13 consists of an additional piece of metal extending outward from the edges H. In the case of the interior member ID a lug l4 consists of a portion of the metal folded on the inside of the channel.

As the interior channel member ID is pulled out from outer channel member l|,jthe lug Hi impinges. upon the lug l3 and further movement. is stopped. Thus, when the two partsof the hinge check are placed together and the lugs are turned in the proper manner, separation of the two members l0 and I I is prevented by the lugs.

Opposite ends of the channel members l0 and H are turned inward to give the device the appearance of a trough the length of which may be varied. The outer member I I has an end closure I5 while the interior member ID has an end closure l6. Apertures or openings I! are formed in alignment in the endmembers l5 and 16 along what would be the axis of rotation of the channel members In and H. The apertures I! are disposed to have the pintle of a hinge inserted therethrough. The channel members it! and II are cut away around the end closures I5 and IS in order to allow spring tension to exist around the edges of the channel members In and II.

The degree any particular hinge is allowed to open depends upon the design of the hinge itself and also upon the degree of angular opening of the hinge check device. Normally the device is adjusted to check further opening of the hinge after the door has opened to about a angle. By "making the device of sheet metal, which may be deformed by forcing the door to a wide aperture after the device has already impinged upon the door hinge plates, it is possible to control the angle 'at which the checking takes place. This may be seen from Figure 2 where a pintle' l8 extends through hinge plates [9 and-also through one of openings I! of the checking device. The edges i2 of the checking device impinge upon the hinge plates l9 and prevent further opening of thejhinge after about a 90 angle ha been reached. If it is desired to have the door open to more than a 90 angle before being checked, it is only necessary to force the side 12 further apart by pushing on the door until the checking device is deformed.

In placing the device of Figure 3 upon a hinge it is only necessary to remove the pintle or hinge pin [8. The checking device is then adjusted to the proper length over the hinge and the pin 18 inserted through openings I1 and hinge plates l9. A single hinge equipped with this door check will prevent a door from impinging against the wall, but if each hinge is equipped with such a check device the control of the door is more permanently accomplished.

Figure 1 shows the hinge check device in place on a hinge. The light, easily installed device is quiet in operation. It has the advantage over the rod type door stop in that a door is checked at an angle of 90 or slightly greater, and consequently a door caught by the wind is checked before it can gain enough momentum to do great damage either to itself or to the wall around it.

From the above description it should be understood that this invention provides a door check the construction of which may be varied through a wide range without departing'from the principles of this invention, and it is,.therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.

We claim as our invention:

1. A door hinge check comprising two telescoping channel sections closed at opposite ends, the other ends thereof being open and provided with e n the open en s t p v nt s pa ation of said sections, and aligned apertures through ac Q d ed en s said pe ur s bei disposed for the passage therethrough of ahinge pintle.

2- A doo in e k c mpr ng two roun bo m c ne which telescope into ea h ther,

the outer of said channels havingthe edgesv 4 channel members loosely enough to permit said inner channel member to slide back and forth, opposite ends of said channel members being folded inwardly whereby said channel members cooperate to form a single trough-like member which may be varied in length by sliding said inner channel member back and forth, and an aperture in each folded inward end. said apertures being disposed for the passage therethrough of a hinge pintle. I

4. A door hinge check comprising two rounded channel members disposed to telescope one within the other, opposite ends of each channel member having a folded inward portion, and an aperture in each of said folded inward ends, said apertures cooperating to form a passageway for a hinge pintle.

5.'A door hinge stop comprising two sheet' metal channel members of semi-circular cross section disposed to telescope one within the other, means for closing one end of each of said channel members, and an aperture in each of said closing means, said apertures forming a passageway for the pin of a hinge.

6. A check for a hinge having a pintle joining a pair of hinge plates for relative hinged movement thereabout, comprising a pair of telescoping channel members, one of said channel members having spaced inturned terminal edges slidably engaging the other .of said channel members and forming resilient arms for abutting said plates upon relative opening movement of said plates about said pintle, and the opposite ends of said telescoping channel members being inturned and extending along opposite ends a:
